by Srizana Ghimire 11 Sep 2025 0 Comments


Our beginner guide shows how to build a nano aquarium tank. Read about 10L and 11L nano aquarium fish tanks, obligatory equipment, the nitrogen cycle, and guidelines on how to set it up step by step. Fits in a small area and is easy to use by novice fishkeepers.

Introduction: Understanding Nano Aquariums

A nano aquarium tank is a small-sized aquarium, typically 10L to 30L, designed to hold small fish, shrimp, and prolifically planted aquatic life. They are mostly used in urban houses as they add nature to small areas such as apartments, desks, and countertops. They are a good beginner aquarium since they allow a novice to get into the fishkeeping experience without the burden of a bigger tank.

A nano aquarium fish tank is versatile, and this is one of the largest attractions of the tank. It can be a shrimp-only aquarium, a miniature school of colourful fish, or a gorgeous planted aquarium, and a nano aquarium will do it. Even a small tank with the appropriate nano aquarium design can appear as a living artwork.

They are popular with many hobbyists because of their space-saving design and also because of their aesthetic look. A properly maintained nano tank can be easily fitted to the centre of any room, indicating that size does not necessarily matter when it comes to aquariums.

Popular Nano Tank Sizes

1. 10L Nano Tank

One of the tiniest available is a 10L nano tank, which is best suited to shrimp and small fish species. These tanks can be used by extreme beginners and those who desire a simple, straightforward setup. You can consider such alternatives as the Petworx Nano Mini 10L, unless you are a beginner.

The advantage of selecting this size is that it is simple to maintain, less expensive, and does not need much equipment. Nonetheless, the limited amount of water also implies that water parameters are changeable rather rapidly, and it is vital to be consistent in care.

2. 11L Nano Tank

A little bigger, at 11L of nano aquarium fish tank, can afford a little more freedom, yet remains small. Fish tanks such as the 11L Nano Aquarium Fish Tank do well to hold shrimp colonies or some small fish species in a planted environment.

This is a decent size that is a compromise between small and stable. With the additional litre of water, it is easier to control the quality of the water, which is good enough for beginners, yet in the initial stages of learning how to keep fish.

3. 22L Nano Tanks

A 22L nano tank is an ideal option for those who wish to increase their hobby a bit. It gives a chance to have a more eclectic community of small fish, additional shrimp, and more vegetation. Smaller water volume causes the environment to be less stable, which increases the likelihood of unexpected variability.

The 22L tank would be the ideal choice for any person who wishes to experiment with aquascaping or test more advanced systems. It is also easier to use for beginners and leaves more room for creativity.

Choosing Stock for Your Nano Aquarium

1. Suitable Species of Nano Aquarium Fish Tank.

When filling a nano aquarium tank, one should choose small, non-aggressive species of fish. Popular include Neon Tetra, Guppies, and Endler Live Bears. These fish are colourful, active and depend on small fish tanks thus, beginner aquarists are safe in keeping these fish.

2. Shrimp Varieties That Thrive

Shrimp are the best choice when using nano because they are small, efficient removers, and attractive to see. A species like Cherry Shrimp, Amano Shrimp, and Crystal Red Shrimp may add colour and movement to your tank besides aiding in the reduction of algae. Shrimp do well under a planted tank where they are free to forage and hide.

3. Beginner-Friendly Species

In the case of a total beginner, it is essential to select tough species. Nerite Snails, small schooling fish, and shrimp would be a great choice since they can forgive small mistakes that usually occur during training. They also do not need much maintenance, thus they need less feeding and care than larger, more sensitive species.

Essential Equipment for Nano Aquarium Setup

1. Filters, Lighting, and Heating

Even a small tank requires the necessary gadgets in order to operate well. Nano tanks are most suitable with a soft sponge or internal filter because it does not cause strong currents in the water quality. Light-emitting diodes (LEDs) are used to promote the growth of the plant and to display the colours of fish, and a compact heater is used to maintain the consistency of the temperatures of tropical species.

2. Substrate and Decor Options

The selection of an appropriate substrate not only enhances the appearance of your tank, but it also helps to keep your plants healthy. Planted nano tanks are suggested to be placed in aquarium soil or fine gravel. Exhibit such decorations as driftwood, small rocks, and live plants to provide personality and provide hiding places for fish and shrimp.

3. Compact Tools for Cleaning and Maintenance

The tools are easier to maintain when used with small tanks. Cleaning is made easy with mini siphons, magnetic algae scrapers, and small nets. In order to guarantee the professional outcomes, it is possible to use the services of an aquarium maintenance professional to make your tank look and stay healthy.

Understanding the Nitrogen Cycle

A healthy aquarium is based on a nitrogen cycle tank. The nitrogen cycle transforms the harmful fish waste (ammonia) to nitrites, and the same nitrites are further converted to less harmful nitrates. Fish and shrimp can not survive without this process.

1. What is the Nitrogen Cycle?

It is the natural way in which the good bacteria decompose waste products to safe compounds. Creating this cycle is necessary prior to the introduction of fish or shrimp.

2. How to Cycle a Nano Tank

Nano aquarium cycling is a long process. Add water, substrate, and equipment, and allow the tank to run with beneficial bacteria added. Check the test water periodically until there is no more ammonia or nitrites, which indicate the cycle is finished.

3. Step-by-Step Nitrogen Cycle for Beginners

    1. Fill the tank with treated water.

    2. Include plants, add substrate, and decor.

    3. Run the filter and heater.

    4. Add a good bacteria starter.

    5. Test water every week until parameters stabilize.

Step-by-Step Nano Aquarium Setup Guide

  1. Select your tank size and put it on a solid surface that is not exposed to direct sunshine.

  2. Install filters, heaters, and lighting.

  3. Ready the surface and decorate it with driftwood, rocks, and plants.

  4. Add dechlorinated water to the tank and start cycling.

  5. When cycling, livestock should be introduced slowly after cycling so as not to put stress on the ecosystem.

This step-by-step method will make sure your tank level sets a stable environment. In a hurry to hurry the process, it frequently results in unhealthy water, which puts a strain on the fish and shrimp.

Ongoing Maintenance and Care

A new nano aquarium must be taken care of regularly to stay healthy. A healthy environment is provided by weekly changing water, measuring water parameters, and feeding times.

Periodic cleaning of spots helps in avoiding algae growth, whereas feeding fish in small portions maintains the amount of waste under control.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
